[Fedora-xen] Virt-manager does not connect to libvirt/Xen? Xen 4.1.5 installed from source on Fedora 17.

Thanks for replying Dario,


Yes, I saw your other e-mail too, but I'm afraid I can't help much as I

I just want to get couple of DomUs running, that is all. I'm not particular
about which tool I use.
Virt-manager seemed easier/quicker, hence I picked that.

I did some reading on configuring DomUs using xl/xm and cfg files.

http://www.fclose.com/w/Setting_Up_Xen_DomU_on_Fedora:_Unmodified_Fedora_on_Top_of_Xenified_Fedora_Xen_Dom0%23Install_Fedora_12_Linux_via_Internet

So basically I create the cfg file, and do "xm/xl create xmf16install -c"
This is one of my cfg files.

name="xmf16install"
memory=2048
vcpus=1
disk=['phy:/dev/xenvg/xmf16lvm,xvda,w']
vif = [ 'bridge=br0' ]
kernel = "/home/fedora16pxe/vmlinuz"
ramdisk = "/home/fedora16pxe/initrd.img"
onreboot = 'restart'
oncrash = 'restart'

The CentOS/Fedora installers are being launched, but I think I am running
into a problem when the installers ask for HTTP location from where to
pickup the images for install. I got different kinds of errors each time (I
tried multiple installations (F15,16, F17, CentOS5).

Some of the errors I got from the anaconda installers were
(F12, CentOS5)
'' loader received SIGSEGV!  Backtrace:

I am guessing there is a problem when it tries to connect to the internet
to download packages.
I have also attached my domU cfg file for reference in the email.

Could someone point out where am I going wrong ?

I just want to get couple of DomUs working and this is proving tougher than
I thought. :(
Is there something wrong with my cfg files. Or is something else the issue
here ?

This was what I tried initially. Regular F17, then yum install Xen, and
Virt-manager just worked out of the box for me, and I was able to create
DomUs.

Sorry, I just seem to be running into multiple issues with this! Kindly
help.
Any pointers would be greatly appreciated.

If all else fails, I am willing to start with a fresh install of F18 as
Dom0 and try to install Xen from source on that. Would this help ? I
remember you telling me F18 with Xen 4.2 working well with the Virt-tools.
